Hey, just noticed on the official site it lists the Recommended fuel to be used as Regular. At a 10.7:1 Ratio! That's surprising to me, I would think you'd be setting off the knock sensor like mad. It also states Premium rec. for increased performance. Does that mean they dyno'ed it with 87 octane and that we'll get more than 426HP out of the LS3 simply by switching up to premium? If so, sweet. I buy premium today, mpg won't be changing. But I'll be getting another 180 HP+. Sweetness.
